Stargazers will witness a partial lunar eclipse on July 16 and July 17, with people in India getting to watch the celestial event on July 17. Partial lunar eclipse, as the name suggests, takes place when the shadow of Earth covers only a small part of the Moon and as a result, only a minor section of the Moon appears dark. The upcoming lunar eclipse will be the last one to happen in 2019 and it will be visible in a majority of Africa, Asia, Australia, Europe, and South America. The timing of this lunar eclipse is pretty interesting as it coincides with the 50th anniversary of the launch of Apollo 11 mission that first landed humans on the Moon. Here's everything you need to know about partial lunar eclipse 2019.
As mentioned above, the partial lunar eclipse will be visible in the majority of Asian nations, including India. The people living in the western and central region of India will witness the entire event, while those living in the eastern regions will get to see the partial lunar eclipse at moonset time in the wee hours.
The Moon will enter the penumbra on July 17 at 12:13am IST and will enter the umbra region at 1:31am IST. The intensity of the partial lunar eclipse will be highest (the time at which at the largest chunk of moon will be covered by Earth's shadow and thus, will appear dark) at 3:00am India time.
The Moon will leave the umbra region at 4:29am IST, which also marks the end of the partial lunar eclipse. The Moon will exit the penumbra region at 5:47am IST, as per NASA's data. The total eclipse duration will be 2 hours, 57 minutes and 56 seconds.
As mentioned above, the partial lunar eclipse that will be visible on July 17 (July 16 in some regions of the globe) will be the last lunar eclipse – partial or global – that will happen in 2019. The only other lunar eclipse recorded this year was witnessed in January and it was a total lunar eclipse.
As for the July 17 partial lunar eclipse, the penumbral magnitude will be 1.7037 and the umbral magnitude will be 0.653. As per the eclipse map released by NASA, the event won't be visible in North America and Greenland.
When the Earth comes in between the Moon and the Sun and casts its shadow over the Moon, cutting off its source of illumination and making parts of it appear dark, the event is caused a lunar eclipse. When the Moon is fully covered by Earth's shadow, it is called a full lunar eclipse, but when only a small portion of the moon appears dark due to incomplete overlapping, it is called a partial lunar eclipse.
The partial eclipse happening tomorrow is a little special for people in India as it marks a coincidence happening after 149 years. The Guru Purnima celebrated in India will happen on the same day as the upcoming partial lunar eclipse for the first time after a span of 149 years. And if you believe in astrology, this coincidence can be of special religious significance.
